读取名称列表会导致错误“重复计数太大”

我有一个包含姓名列表的程序:

implicit none
real,dimension(20)::Rc,Ic
integer::n_cyl,degree=4
namelist /vars/ n_cyl,degree,Rc,Ic
open(1,file='vars.txt')
read(1,nml=vars)  ! line 19
close(1)
! ..............
open(1,file='vars.txt',STATUS='UNKNOWN',RECL=1000)
write(1,nml=vars)
close(1)
end

变量.txt:

&VARS
 N_CYL=         12,
 DEGREE=          4,
 RC= 0.256000012    , 0.512000024    , 0.768000007    ,  1.02400005    ,  1.27999997    ,

如果在Linux上使用gfortran进行编译,则它可以正常工作,但是在MinGW(Win32)上使用gfortran进行编译并运行时,它会抛出一个错误:

At line 19 of file elen.f90 (unit = 1, file = 'vars.txt'):
Fortran runtime error: Repeat count too large for namelist object rc

这是一个bug,还是代码中有问题?
